Very good. but Acryllic will go yellow in 3-5 years from new due to UV exposure in outdoors resulting in yellowish tint on images taken with your super lens. Harry. this is not a good idea..I don't want it to be a disposable lens, I just want it to be a FAST lens!
And modern plastics with 1.54 and 1.77 index of refractions ARE the way to go... giving us LIGHT WEIGHT AND FAST LENSES !!!
It means we CAN have that 95-800 mm Sigma Sports Zoom at f4.0 to f/5.6 that is LIGHTER and shorter than today's Sigma 150-to-600 mm sports zoom!
I'll pay DECENT MONEY for that ability!
